About the Variegated Longhorn
Coptomma variegatum, also known by the names variegated longhorn and tawa longhorn, is a species of longhorn beetle that is endemic to New Zealand. The species was one of the first 40 New Zealand insect species to be described, and was collected by naturalists as a part of the Second voyage of James Cook. Upon return to the United Kingdom, the species was described by Johan Christian Fabricius in 1755, who used the name Callidium variegatum. In 1840, British entomologist Edward Newman created the genus Coptomma, describing Coptomma virgatum as the type species for the genus. In 1843, German entomologist Ernst Dieffenbach synonymised Callidium variegatum and Coptomma virgatum, leading to the modern scientific name Coptomma variegatum.
The holotype of the species was deposited in John George Children's collection of beetles in London, but has since been lost. The two original descriptions by Fabricius and Newman identified the species as being a native of Australia, which was incorrect.
The species can grow up to 22 mm (0.87 in) in length. Coptomma variegatum is visually similar to the genus Navomorpha, but can be identified by the pronotum of Coptomma... Wikipedia →
